We work on patio & French doors, aluminium frames and uPVC windows, and common reasons people get in touch are cold air getting in at the frame edge and draughty joints inside around the window.
In a village or hamlet like Monxton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Windows and doors in Monxton
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Andover station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Amport Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What sealant work cannot fix
We will always be straight with you, so here’s what sealant cannot fix:

- Penetrating damp from a failed cavity tray or render
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

- Window sills

What we do, step by step
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. Somewhere as small as Monxton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

For landlords and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Common questions in Monxton
Do you cover Monxton for window mastic?
Yes, Monxton is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Do you cover smaller places like Monxton?
Yes. Monxton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Is the new sealant paintable?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. You will get a timescale with the quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Ventilate rooms so frames do not stay wet inside
- Repaint timber before it’s bare
- Make sure the drainage slots aren’t blocked
- Keep paint off silicone joints
Most silicone sealants will not take paint, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
